We reported the tritium release enhancement from liquid LiPb droplets under partial nozzle emission. The release from the partial LiPb flow in an inlet pipe is estimated as an enhancement factor. Analysis is performed with the parallel flow one direction release model. Extraction efficiency is deduced by the multiplication of a static release ratio and an enhancement Sherwood number by Hanna. Obtained enhancements are from 75 to 85 % of the theoretical estimation. Contribution of the partial flow inside tube is confirmed.
